Still further, system 26 provides this integrated functionality in a single central processor. This allows system 26 to adjust the protection functions of each brealcer 14, 114, 214, 314 in the system based on the state of that brealcer as sampled by first and second signals 38, 40, as well as based on the status of any and/or all of the other breakers in the system.
